On another of my blogs I noticed a severe problem this morning. It would start to load and then, once almost fully loaded it would switch to a blank page and hang indefinitely. According to my browser it was waiting for b.scorecardreasearch.com.

After doing some Googling I found that there's been a lot of this going on. There are sites that are using a script from scorecardresearch.com in their widgets and apparently that script is broken, at least as far as Firefox 3.6 is concerned and it's making sites not work as a result.

I did some trial and error testing and found that when I removed the Technorati widget from the blog in question, the problem stopped. Therefore, until somebody fixes it, I recommend turning off or removing Technorati and any other widgets that use scripts from scorecardresearch.com.

It seems they're trying to build a web bug from javascript instead of using the traditional 1x1 or 0x0 pixel image that's been in use for a long time.

Short answer: scorecardresearch (apparently associated with Comscore) needs to go, it's breaking websites all over the place.
